Flanges Gasketes



Flanges Gasketes

FLANGES, GASKETS & FLANGE INSULATTION KIT

The company produces flanges according to most European and International norms as: UNI, EN, BS, ASME, API, AWWA, NORSOK, each one referring to a specific industrial sector.

Considering the different applications, flanges follow certain rules that define the typology, dimensions and materials more suitable to the specific requirements.

There are different types of ASME flanges depending on specific needs. They are divided into 7 classes of pressure, which is indicated in pounds per square inch (PSI).

 

Dimensions:
                                     
Flanges, Rings, Discs and Special Forgings:                                            
Dimensions from 1/2'' till 120''
Dimensions from DN15 till DN3000
Pressure from 150 lbs, 300 lbs, 600 lbs, 900 lbs, 1500 lbs till 2500 lbs
